How much do children with disabilities participate in Clinical Trials? A Scoping review.

BACKGROUND: Children with disabilities (CWDs) are often excluded from scientific research, but no precise data are available on their participation in Clinical Trials. The aim of this study was to evaluate the rates of exclusion of CWDs from recent medical research. SUBJECTS AND METHODS: The protocol of the study was designed according to Prisma-ScR guidelines. All completed interventional Clinical Trials registered on Clinicaltrials.gov between 2010 and 2020 related to the Leading 10 Level 3 causes of global Disability-adjusted life years (DALYs) for both sexes combined for all ages of the updated Global Burden of Disease Study 2019 were analysed. The exclusion criteria were considered explicit if related to the following categories: disability, physical impairment, cognitive impairment, behavioural or psychiatric disorders, language and communication impairment, sensory impairment. Any generic or poorly specified exclusion criteria or statements that left wide discretion to researchers were considered "implicit exclusion criteria". We assessed the appropriateness of explicit exclusion criteria in relation to the primary objectives of the trials and labelled them as "absolute", "relative", or "questionable". RESULTS: The trials selected according to the inclusion criteria of the scoping review were 328; 166 (50.6%) were pediatric-only studies, and 162 (49.4%) trials comprising subjects of all ages. Explicit exclusion criteria were found in 82 trials (25%) and the disability category most frequently excluded was "Behavioural or psychiatric disorders" present in 46 trials (56.1%). Explicit exclusion criteria were considered "relative" in over 90% of the selected studies. Implicit exclusion criteria were present in 153 trials (46.6%) and the number and percentage of studies with at least one explicit or implicit exclusion criterion were 193 and 58.8% respectively. CONCLUSIONS: This study highlights a high rate of exclusion of CWDs from medical research and the need for an inclusive approach that comprises the study design and any necessary adaptations for specific needs.

Anxiety Disorders in People with Intellectual Disabilities: the Best Treatment for Properly Modulate Activities of Daily Living.

The article explores the correlation between intellectual disability and anxiety and how much they occur together. People with intellectual disability have comorbidity disorders of all types 3 to 4 times higher than the general population and the anxiety, can create difficulties in the context of social inclusion caused by insecurity and worries felt from who is affected by this pathology.

Pain Assessment in People with Intellectual Disability: Improving Skills of Health and Educational Personnel at Istituto Serafico of Assisi, Italy.

BACKGROUND: Assessment of pain in people with intellectual disability (PWID) is a difficult clinical task. Poor knowledge and confidence in assessing pain in PWID result in underestimation and undertreatment. Available resources for healthcare personnel and caregivers on pain assessment in PWID are still very limited. The aim of the study was to measure the level of knowledge and confidence in assessing pain in PWID of health and education personnel at Istituto Serafico, before and after training. SUBJECTS AND METHODS: The Istituto Serafico is a neuro-rehabilitation center caring for people with complex disabilities. Nurses, rehabilitation therapists, social health workers (SHW) and educators were invited to participate in a 4-hours theoretical and practical training. Participants were assessed through a knowledge and confidence questionnaire on pain assessment in PWID, administered before and after the training. RESULTS: 123 participants attended both the theoretical and practical sessions. Median age was 43 years (range 23-67); 89 were females and 34 males. They were 10 (8%) nurses, 9 (7%) rehabilitation therapists, 77 (63%) SHW, 27 (22%) educators. Only 7 (6%) participants (5 nurses and 2 SHW) declared to have previously received formation on pain. Participants who felt "quite confident" in assessing pain increased from 28% to 73% after the training. The median score to the 24 knowledge questions raised from 15/24 correct answers (range 6-22, 62.5%) in the pre-test to 21/24 (range 11-24, 87.5%) in the post-tests (p=0.001) Conclusions: The study highlights the great need of education programs for health and educational personnel working with PWID on pain assessment and the potential to improve knowledge and confidence through theoretical and practical training. A greater awareness of pain causes, clinical manifestations and consequences of untreated pain, could improve patient care, quality of life and rehabilitation goals.

Mood Disorders in People with Intellectual Disabilities: Diagnosis and Treatment.

Discriminating mood disorders from symptoms of intellectual disability is still a challenge for clinicians. We need standardized tools to apply right diagnoses without confusing signs and symptoms and specially to standardize psychological techniques to treat mood disorders without the use of drugs even in people with intellectual disability.

Intellectual Disability and Psychiatric Disorders as Exclusion Criteria in Randomized Controlled Trials (RCT).

People with intellectual disability or psychiatric disorders are commonly excluded from Randomized Controlled Trials (RCTs) because of explicit exclusion to the trials or because of inaccessible research protocols. We analyzed the exclusion rate of persons with cognitive impairment, psychiatric disorders and inability to give informed consent in interventional RCTs about the first 10 causes of global DALYs (disability- adjusted life-years) according to the Global Burden of Disease Study (GBD) utilizing the website Clinicaltrials.gov. A total of 2809 studies in the 10 selected categories were reviewed. "Cognitive impairment" was present in 488 (17.4%) studies, "Behavioural and psychiatric disorders" was present in 616 (21.9%) studies, "Inability to grant informed consent" was present in 498 (17.7%) studies and the three explicit criteria were present, alone or in combination, in 1076 studies (38.3%). Other disability-related exclusion criteria were considered to be implicit exclusion criteria and were present in 1233 (43.9%) studies. A judgement was made on the correlation between the exclusion criteria and the primary objectives of the studies analyzed. The low level of representation of people with disabilities in RCTs, in addition to being an ethical problem, is a limitation of scientific knowledge because it considerably reduces the external validity of a significant part of medical research. There is a need to review the way scientific research designs are constructed, seeking to promote greater inclusiveness of people with disabilities.

Affective Disorders in Complex Disabilities: Strategies Empowerment for Improving the Lifestyle of the Disabled Person.

The concept of physical and intellectual disability has experienced a series of changes and evolutions over time with regard to approach, classification and rehabilitation-therapeutic programs, since it contemplates a heterogeneous clinical phenomenology in terms of severity, complexity, pervasiveness and severity of the diagnosis. The significant repercussions on the quality of life mean that a comprehensive approach is required with attention to the physical, social, emotional, sensory and cognitive profile, and that there is a need for the adoption of classification systems and assessment tools that are different and in some ways pioneering, so as to guarantee the surpassing of the concept of disability as a "mere defect" physical and/or impairment and/or loss of psychological, physiological or anatomical function (Holden & Gitlesen 2003, Linden 2017, WHO 2001). It is exactly in contemplation of a bio-psycho-social model, that the International Classification of Functioning, Disability and Health (ICF) arises, which possesses a neutral position with respect to etiology and a complementarity with the ICD-10 classification (WHO 2001), since it allows the functional diagnosis (i.e. a specialized analytical description of the potential and deficits in relation to the pathology) proposing a detailed analysis of the possible social consequences of disability by evaluating the residual capacities and measuring the "social skills" (WHO 2001).

'Being disabled' as an exclusion criterion for clinical trials: a scoping review.

BACKGROUND: People with disabilities (PWDs) are often excluded from biomedical research, but comprehensive data regarding their participation in clinical trials are not available. The objective of this study was to assess the rates of exclusion of PWDs from recent medical scientific research. METHODS: The protocol of the study was designed according to PRISMA-ScR (PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) extension for Scoping Reviews) guidelines. All completed interventional clinical trials registered on ClinicalTrials.gov between 2010 and 2020 regarding the 10 leading causes of global disability-adjusted life-years according to the Global Burden of Disease Study were analysed. An exclusion criterion from the study was considered explicit if it could be associated with one of the following seven categories: disability, physical impairment, cognitive impairment, behavioural or psychiatric disorders, language and communication impairment, sensory impairment. Comorbidities not more clearly defined and researcher discretion regarding exclusion of study participants were considered to be 'implicit exclusion criteria'. We assessed the appropriateness of explicit exclusion criteria in relation to the primary objectives of the trials and labelled them as 'absolute', 'relative' or 'questionable'. RESULTS: The total number of trials analysed was 2710; 170 were paediatric trials (6.3%), 2374 were adult trials (87.6%) and 166 were trials including subjects of all ages (6.1%). Explicit exclusion criteria were found in 958 trials (35.3%). The disability category most frequently excluded was behavioural or psychiatric disorders, present in 588 trials (61.4%). In only 3% and 1% of the trials, the exclusion criteria were considered either 'absolute' or 'questionable', while in 96% the exclusion criteria were judged as 'relative'. Implicit exclusion criteria were present in 1205 trials (44.5%). CONCLUSIONS: This study highlights the high rate of exclusion of PWDs from biomedical research and the widespread use of ill-defined exclusion criteria in clinical trials. It underscores the importance of more inclusive study designs so that PWDs can become active participants in research.
